Actually, I am not the only one running those sites. I just created them thats why I was wondering why a site which is getting link from only one site having a PR4 has got PR3. LOL for Google! Anyways guys thanks. I think my doubt is cleared but I still laugh on the criteria with which Google assign PR.
It is not "getting link from one site" it is getting 47 links from 47 pages on one site. 47 pages --> --> --> 1 page See???
Same with me, I have a site that recently I bought from friend and increase into PR 3 in 2 weeks. This is my site iPod Case What do you think about my site?
